A butterfly valve refers to a valve with a closing part (valve disc or butterfly plate) as a disc, which rotates around the valve axis to achieve opening and closing. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Before assembling and using the butterfly valve, the carbon steel surface needs to be derusted and sprayed with anti-corrosion paint. Grinding and rust removal is a common method of metal surface treatment. The following are some commonly used grinding and rust removal techniques: Manual grinding: Using a wire brush or steel sandpaper: Suitable for small areas or complex metal parts; Using a grinding stone or grinding head: Suitable for removing larger rust spots or uneven surfaces; Mechanical grinding: Using an angle grinder with a grinding disc can quickly remove rust, suitable for large areas of metal surfaces.

During the grinding and rust removal process, the wiping ball 504 will wipe the polished part to remove the grinding chips attached to the inner surface of the forty-five-degree butterfly valve body 2 during the grinding process, thereby ensuring the quality of the grinding and rust removal of the forty-five-degree butterfly valve body 2 and the smoothness of the inner surface of the forty-five-degree butterfly valve body 2 after grinding and rust removal. During this process, while the grinding plate 503 is grinding and removing rust from the inner surface of the forty-five degree butterfly valve body 2, while the grinding plate 503 is rotating from the lowest point to the highest point of the inner surface of the forty-five degree butterfly valve body 2, the wiping ball 504 will enter the forty-five degree butterfly valve body 2 from the upper surface of the forty-five degree butterfly valve body 2, and the forty-five degree butterfly valve body 2 will squeeze the wiping ball 504 and then squeeze and push the piston plate 604 to move in the direction of the connecting pipe 602 through the connecting column 605, so that the grinding and polishing liquid in the piston chamber 603 is discharged through the discharge channel 609 to the grinding contact part of the forty-five degree butterfly valve body 2 and the grinding plate 503, so as to promote the cleaning of grinding chips in the grinding parts of the forty-five degree butterfly valve body 2 and the grinding plate 503, and to The forty-five-degree butterfly valve body 2 and the grinding plate 503 are cooled. During this process, the piston chamber 603 draws outside air into the piston chamber 603 through the air inlet channel 607. At the same time, since the grinding plate 503 rotates from the lowest point to the highest point on the inner surface of the forty-five-degree butterfly valve body 2, the wiping ball 504 located in the forty-five-degree butterfly valve body 2 will be separated from the bottom of the forty-five-degree butterfly valve body 2 and automatically restored, so that the piston plate 604 slides outward under the action of the return spring 606, so that the gas in the piston chamber 603 is discharged through the exhaust channel 608, and the grinding chips remaining on the outer surface of the grinding plate 503 are blown away from the grinding plate 503, so as to avoid the existence of the grinding chips affecting the quality of grinding and rust removal of the forty-five-degree butterfly valve body 2 by the grinding plate 503; During the process of the grinding plate 503 rotating from the highest point to the lowest point on the inner surface of the forty-five degree butterfly valve body 2, the wiping ball 504 will enter the forty-five degree butterfly valve body 2 from the lower surface of the forty-five degree butterfly valve body 2, and the forty-five degree butterfly valve body 2 will squeeze the wiping ball 504 and then squeeze and push the piston plate 604 to move in the direction of the connecting pipe 602 through the connecting column 605, so that the grinding and polishing liquid in the piston chamber 603 is discharged through the discharge channel 609 to the grinding contact part of the forty-five degree butterfly valve body 2 and the grinding plate 503, so as to promote the cleaning of the grinding chips in the grinding parts of the forty-five degree butterfly valve body 2 and the grinding plate 503, and to polish the forty-five degree butterfly valve body 2 and the grinding plate 503. Cooling, during this process, the piston chamber 603 draws outside air into the piston chamber 603 through the air inlet channel 607, and at the same time, since the grinding plate 503 rotates from the highest point to the lowest point on the inner surface of the forty-five-degree butterfly valve body 2, the wiping ball 504 located in the forty-five-degree butterfly valve body 2 will be separated from the top of the forty-five-degree butterfly valve body 2 and automatically restored, and then the piston plate 604 slides outward under the action of the return spring 606, so that the gas in the piston chamber 603 is discharged through the exhaust channel 608, and the grinding chips in the grinding parts of the grinding plate 503 and the forty-five-degree butterfly valve body 2 are blown away from the grinding plate 503 and the forty-five-degree butterfly valve body 2, thereby improving the discharge efficiency of the grinding chips; And in this process, the gas and grinding and polishing liquid in the piston chamber 603 can absorb the temperature of the grinding plate 503 generated by grinding and polishing, thereby further cooling the grinding plate 503 and the forty-five degree butterfly valve body 2, preventing the grinding plate 503 and the forty-five degree butterfly valve body 2 from softening, which affects the service life of the grinding plate 503 and the grinding and rust removal quality of the forty-five degree butterfly valve body 2. In addition, since the grinding and polishing liquid absorbs the temperature generated by the grinding and polishing of the grinding plate 503, the grinding and polishing liquid will be heated, thereby reducing the viscosity of the grinding and polishing liquid and enhancing its fluidity, so that the polishing liquid can be more evenly covered on the inner surface of the forty-five degree butterfly valve body 2, thereby improving the consistency of polishing, and heating helps the abrasive in the polishing liquid to more effectively remove oxides and tiny defects on the surface of the steel, thereby improving the surface finish. In addition, heating helps to soften or dissolve the debris generated during the polishing process, making it easier to separate from the inner surface of the forty-five degree butterfly valve body 2; At the same time, the grinding and polishing liquid entering the grinding part will be filtered by the filter screen 307 after carrying out the grinding chips, and then flow to the inner bottom of the collecting cylinder 305. At this time, due to the rotation of the rotating shaft 402, the piston plate 404 will slide up and down in the piston cylinder 403. When the piston plate 404 slides from bottom to top along the inner wall of the piston cylinder 403, the piston cylinder 403 will extract the filtered clean grinding and polishing liquid through the liquid extraction hole 405. When the piston plate 404 slides from top to bottom along the inner wall of the piston cylinder 403, the clean grinding and polishing liquid in the piston cylinder 403 will enter the hollow groove 406 through the liquid inlet hole 407 under the action of extrusion, and then enter the liquid tank 501 for use in grinding and rust removal. After grinding and rust removal is completed, turn off the motor 401 and then start the electric telescopic rod 502 to move the grinding plate 503 inward away from the forty-five-degree butterfly valve body 2. At this time, the forty-five-degree butterfly valve body 2 after grinding and rust removal can be removed from the top of the supporting column 301, and then open the impurity discharge door 306 to clean the impurities filtered by the filter screen 307. When it is necessary to replace the grinding and polishing liquid, it is only necessary to open the valve in the exhaust pipe 308 during the grinding and rust removal process.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
